The issue you're having is that with PaperSpace it's (to put it simply) a sheet of paper with a hole or multiple holes cut into it so that you can see beyond into ModelSpace. In MS it makes no difference WHERE the entities are located - just that you have to center your PS viewport over what you want it to show and give it an XP factor (ie. if you want an 1/8" plan you'd start out in PS, then double click into the viewport, zoom out/in (or pan around) so that you see the plan, then tell Acad to zoom at 1/96xp, then click back outside the viewport).
I don't think there is any way to have what you see in PS show up in MS, since what's really drawn in Acad IS in MS.
Clear as mud now? What you REALLY want to tell the consultant is that EVERYTHING must be drawn in MS - NOTHING allowed in PS. This way you'll have it show up in Dcad the way that you want it.
